用ServerAlias

<VirtualHost *:80>
ServerAdmin i@kuigg.com
DocumentRoot /www/kuigg.com
ServerName kuigg.com
ServerAlias  www.kuigg.com  abc.kuigg.com
</VirtualHost>

或者用下面的笨方法

<VirtualHost *:80>
ServerAdmin i@kuigg.com
DocumentRoot /www/kuigg.com
ServerName kuigg.com
</VirtualHost>

<VirtualHost *:80>
ServerAdmin i@kuigg.com
DocumentRoot /www/kuigg.com
ServerName www.kuigg.com
</VirtualHost>

<VirtualHost *:80>
ServerAdmin i@kuigg.com
DocumentRoot /www/kuigg.com
ServerName abc.kuigg.com
</VirtualHost>
